In the landscape of modern precision manufacturing, product purity is no longer just a quality metric—it is a fundamental requirement that defines market access, regulatory compliance, and brand trust. For industries where even microscopic contamination can render a product unusable or unsafe, the choice of molding technology directly impacts business success. At Guangdong Lixun Machinery Technology Co., Ltd. , we have engineered our comprehensive range of fully electric injection molding machines—from the compact 5-ton to the formidable 450-ton model—to deliver exceptional performance in a completely oil-free environment, setting new standards for cleanliness in injection molding .
Why Oil-Free Operation is Revolutionizing Clean Manufacturing
Traditional hydraulic injection molding machines rely on substantial volumes of hydraulic oil to generate power and control motion. This dependence creates inherent and unavoidable risks that compromise product quality and workplace safety:
Leaks from seals and fittings that develop over time, allowing oil to escape onto molds, parts, and floors
Spills during maintenance that create slip hazards and contamination events
Vapor emissions from heated oil that can condense on surfaces and contaminate sensitive products
Microscopic oil mist that spreads throughout the workshop, settling on everything
Degraded oil that forms sludge and varnish, contaminating the hydraulic system itself
For manufacturers in medical devices, food packaging, optics, and electronics, these risks are not just operational inconveniences—they are existential threats to quality and compliance. A single oil leak can ruin an entire production batch, trigger a customer complaint, or cause a regulatory finding that jeopardizes market access.
Guangdong Lixun's all-electric injection molding machines eliminate these concerns entirely, providing a fundamentally cleaner, safer, and more sustainable production platform that protects both your products and your reputation.
The Lixun Clean Advantage: Zero Oil, Zero Compromise
Complete Elimination of Hydraulic Oil
Every Lixun fully electric injection molding machine operates without a single drop of hydraulic fluid. By replacing complex hydraulic systems with advanced servo-electric drives, we彻底eliminate the risk of oil leakage that plagues conventional machines. There are no:Your products emerge from the mold pristine—free from oil contamination that can cause defects, trigger rejects, and necessitate costly cleaning operations. Your molds remain clean, requiring less frequent maintenance. Your workshop floors stay dry and safe, without the constant housekeeping burden of hydraulic systems.
Consider the contrast with hydraulic technology: even a well-maintained hydraulic machine experiences minor leakage over time. Seals degrade, fittings loosen, and microscopic amounts of oil vapor enter the atmosphere. In cleanroom environments, this contamination can compromise entire production batches. Lixun electric machines eliminate this risk at its source.
Hydraulic pumps to wear and leak
Valves to stick and bypass
Hoses to rupture and spray
Seals to degrade and drip
Reservoirs to vent and mist
Filters to change and dispose
Ideal for High-Purity Industries
The Guangdong Lixun electric injection molding machine is the preferred choice for applications where cleanliness is not just desirable but mandatory:By removing oil from the production environment, you achieve higher yields, reduced rejection rates, and enhanced regulatory compliance—all without compromising productivity.
Medical Devices: No risk of oil contamination ensures compliance with stringent ISO 13485, FDA 21 CFR Part 820, and GMP requirements. Devices emerge from the mold clean, eliminating the need for post-molding cleaning and reducing bioburden risk. For implantable devices, the absence of potential contaminants is essential for biocompatibility.
Food Packaging: Eliminates concerns about oil migration or food contact safety. Packages can be produced with confidence that no hydraulic fluids will contaminate food-contact surfaces, meeting FDA food contact requirements and avoiding costly recalls.
Optical Components: Guarantees crystal-clear surfaces free from oil residues, haze, or films that can degrade optical performance. For lenses, light guides, and display components, this clarity is essential.
Electronics: Prevents oil-related failures in sensitive components and connectors, where even invisible contamination can cause intermittent electrical issues or long-term reliability problems.
Pharmaceutical Packaging: Meets the strictest requirements for container cleanliness and absence of extractables/leachables.
Reduced Operating Costs & Environmental Impact
The benefits of oil-free operation extend far beyond product quality to directly impact your bottom line and environmental footprint:These savings compound over the machine's lifetime, contributing to a lower total cost of ownership while supporting your sustainability goals.
No Oil Purchase Costs: Eliminate recurring expenses for hydraulic fluid procurement, which for large machines can represent thousands of dollars annually. A 450-ton hydraulic press may hold 500+ liters of oil, requiring initial fill and periodic replacement.
No Oil Maintenance: No need for oil filtration systems, testing programs, or scheduled fluid replacement. No labor for oil changes. No disposal contracts.
No Waste Oil Disposal: Reduce hazardous waste generation and associated disposal costs, simplifying environmental compliance.
Simplified Spill Response: No need for spill containment equipment, absorbent materials, or emergency response protocols.
Lower Insurance & Compliance Burden: Minimize risks associated with oil spills, environmental violations, and worker exposure to petroleum products.
Cleaner Workplace: Eliminate slippery floors, oil mist in the air, and the constant housekeeping burden of hydraulic systems.
Real-World Clean: Applications Transformed by Lixun Oil-Free Technology
Medical Device Manufacturer: A producer of insulin pen components struggled with oil-related rejects on hydraulic machines. Despite careful maintenance, occasional leaks contaminated parts, requiring post-molding washing that added cost and extended cycle time. After transitioning to Lixun 50-ton and 100-ton electric machines, oil-related rejects dropped to zero, washing operations were eliminated, and cycle time decreased by 15%.
Food Packaging Manufacturer: A manufacturer of microwaveable food containers faced recurring complaints about oil spots on packaging surfaces. After replacing their hydraulic fleet with Lixun 150-ton and 220-ton electric machines, oil-related complaints dropped to zero, and the company eliminated its container-washing operation, saving $80,000 annually.
Optical Component Producer: A producer of high-end camera lens elements required absolute surface purity. Hydraulic machines could not consistently achieve the required cleanliness without extensive post-processing. Lixun 30-ton and 50-ton electric machines now produce lens elements that meet optical specifications directly from the mold, eliminating polishing and cleaning steps and reducing production time by 40%.
